bug#51831: 29.0.50; Region not highlighted

[Carlos Pita]

Hi all,

after typing ctrl-space and moving the point around, the region
is not being highlighted.

This was tested running emacs -q on a build from recent master.

I verified that transient-mark-mode was enabled. Other than the
missing highlight, the behavior is as expected.

Maybe of interest: shift-arrows selection does highlight the region.

Best regards,
Carlos
